Immerse yourself in the forefront of concrete innovation with BT-302, a revolutionary superplasticizer designed for superior slump retention and fast-release efficacy. Crafted from TPEG through sophisticated free radical polymerization, BT-302 introduces a cutting-edge sustained-release group. In concrete's alkaline environment, this slow-release marvel gradually unleashes a dispersive function group, ensuring cement particles remain optimally dispersed, significantly curbing concrete slump loss. Despite its modest water reduction capability, BT-302's unparalleled slump protection is unrivaled, making it the preferred choice alongside water-reducing mother liquors like JS-101B and JS-101A. Perfectly engineered for high-strength concrete applications requiring exceptional slump retention, BT-302 reigns supreme in diverse engineering challenges, from pumping and super-flow self-compacting concrete to high-performance infrastructures like high-speed railways, expressways, hydropower stations, and monumental projects.
2. Revel in its unmatched ability to maintain concrete slump, ensuring it stays intact for an impressive duration of up to 2 hours without any decrement.
3. Though its water reduction rate is minimal, necessitating synergy with water-reducing mother liquors, the amalgamated result is nothing short of extraordinary.
4. With its remarkably low viscosity and thixotropic nature, BT-302 is the ideal companion for concrete mixes featuring a reduced water-cement ratio.

2. BT-302 is the cornerstone of construction in high-speed railways, nuclear power plants, water conservancy projects, subways, large-scale bridges, expressways, harbors, and wharves, becoming indispensable for national mega-projects and critical infrastructure ventures.
3. Be it industrial or civil construction projects or commercial concrete mixing stations, BT-302's versatility is limitless, adapting seamlessly to any project requirement.
1. As a colorless or light yellow liquid, BT-302 is best used by combining 0-20% of its mother liquor with a water-reducing counterpart. Blend with additional minor components to craft a potent water-reducing agent, typically dosed at 1% to 3% of total cement material weight.
2. Before employing BT-302 or switching cement and gravel types and batches, conduct adaptability testing with the specific materials. Use test findings to establish the optimal water-reducing agent proportion.
3. While BT-302 can function solo, it's generally advised to pair it with water-reducing and set-retarding mother liquors for maximum slump loss mitigation. Alternatively, combine it with functional aids to create admixtures with attributes like retarding, early strength, antifreeze, or enhanced pumping. Application techniques and conditions should always be guided by rigorous testing and compounding expertise.
4. BT-302 syncs harmoniously with other admixtures, such as early strength agents, air-entraining agents, and retarders. Ensure compatibility through preliminary testing. Avoid combining with naphthalene-based water reducers to maintain product integrity.
5. Define concrete cement and mix ratios through precise testing. During application, simultaneously integrate the blended and measured water into the concrete mixer post-mixing test completion to guarantee unmatched concrete quality.
6. When active admixtures like fly ash and slag are part of the mix, determine the water-reducing agent's proportion relative to the total cement material weight to optimize performance.
